Starter Replacement Coils
Starter replacement coils and equipment replacements are essential for maintaining the reliability and longevity of industrial motor control systems. RSP Supply carries a wide selection of starter replacement coils from trusted manufacturers such as Schneider Electric and Eaton, including heater coils and Type S starter coils used in a variety of motor starter and contactor assemblies. These components allow maintenance and repair of existing equipment without replacing complete starters.
Contactors are electrically operated switching devices used to control high-current loads, most commonly electric motors. When a starter coil is energized, it creates a magnetic field that closes the contactor contacts and allows current to flow to the motor. Replacing a worn or failed coil restores proper electromagnetic operation, ensuring reliable motor starting and stopping under both manual and automatic control conditions.
Heater coils are used in thermal overload relay assemblies to provide motor overload protection by generating heat proportional to motor current. When excessive current is detected, the heater coil contributes to tripping the overload mechanism and disconnecting power to the motor. Type S starter coils are commonly used in specific starter designs and must be correctly matched to voltage and application requirements to ensure safe and dependable operation.
FAQs
Q: What is a starter replacement coil?
A starter replacement coil is a component used to restore the electromagnetic operation of a contactor, allowing it to open and close power contacts properly.
Q: What causes contactor coils to fail?
Coil failure can result from incorrect voltage, overheating, extended duty cycles, electrical surges, or general wear over time.
Q: Can replacement coils be used instead of replacing the entire contactor?
Yes, replacing a failed coil is often a cost-effective way to restore contactor function without replacing the entire device, provided the contacts and mechanical components are still in good condition.
Q: How do I select the correct replacement coil?
The replacement coil must match the original coil’s voltage rating, frequency, and manufacturer specifications to ensure proper operation and compatibility.
Q: Are starter replacement coils used only in motor control applications?
While most commonly used in motor control systems, starter replacement coils can also be used in other high-current switching applications that rely on contactors.
